Bad Simplicity

• Install:

• sudo apt-get install libavformat-dev libavcodec-dev libavfilter-dev libswscale-dev

• Download an compile OpenCV, it’s better and it takes only a few minutes to compile.
• OpenCV changed the API, all these examples that import “highgui” and “cv2.cv” and so are wrong! Now you have to use:

import cv

• Problem capturing keys? waitKey() doesn’t return strings or chars! instead it returns a that number you need to mask with 255:

 my_key = chr(cv.waitKey(10) & 255)

• Cannot capture from your camera?

http://stackoverflow.com/questions/4749498/cant-access-webcam-with-opencv

• Install libv4l-dev before compiling in Ubuntu or your camera will not capture anything (empty window).
• «if you only have one camera, or you don’t care which camera is the correct one, then use “-1″ as the index. Ie for your example capture = cv.CaptureFromCAM(-1).»

• Use cv.CV_FOURCC() for getting the code for video codecs (en c++ it’s a macro).

• Load the classifiers (for face detection for example) using

classifier = cv.Load("/full/path/to/opencv/share/classifier.xml")
